This is a broken-in Power Dash motor. The break-in was performed with a small amount of oil at low voltage. The rotation speed was measured at 3V using Motor Boot Camp 2. Please note that the rotation speed is an estimate. The break-in method leaves high torque, so the acceleration feeling remains, and it is thought to be fast enough even on a three-dimensional course. I have actually run it with the same break-in method and confirmed the torque and speed. Since it has not been used after break-in, it will be listed as unused. Since it will be shipped after being sold after break-in, the motor is stored in a box with a desiccant, but please note that the condition may change during transportation. Even if the rotation speed drops slightly, it will still be fast enough. Please try it. PLM oil is used for storage after break-in. Returns and exchanges are not accepted to prevent replacement. #Mini4WD #PowerSource #PowerSo #MachDash #SprintDash #HyperDash #PowerDash #MotorBreakIn #HighRotation #SuperFastMotor
